The training on Intel compilers, tools, and libraries will be this Tuesday, March 6, 2018. The training, which will be presented by experts from Intel, will cover topics including using Intel's compilers, tools, and MPI. The following day, there will be a KNL hackathon, with Intel and NERSC experts on hand to help you evaluate the performance of your application and develop an optimization strategy. We encourage you to participate in both events if possible. See <https://www.nersc.gov/users/training/events/intel-compilers-tools-and-libraries-training-march-6-2018/> and <https://www.nersc.gov/users/training/events/cori-knl-hackathon-march-7-2018/> for details and registration. ## New User Training March 21 at NERSC <a name="training"/> ## We will hold a one-day training event for new users on Wednesday, March 21, 2018 to provide users new to NERSC with the basics for using NERSC systems. Topics include accounts and allocations, programming environment, tools, best practices and the data-intensive science ecosystem. The event will be held at LBL's Shyh Wang Hall (Building 59, CRT) in Room 4102. All sessions will presented online using Zoom but we highly recommend attending in-person if you can. See <https://goo.gl/6nLbUi> for details and registration. ## NUG Webinar Next Thursday <a name="nug"/> ## The NERSC User Group (NUG) monthly webinar will be held next Thursday, March 15 from 11 am to noon PST. The agenda includes NUGEX elections. For more information, including connection info, please see <https://www.nersc.gov/users/NUG/teleconferences/nug-webinar-march-15-2018/>. ## Quarterly Allocation Adjustments on April 10 <a name="allocred"/> ## Computational repositories that are not ALCC or DDR projects and have not charged significant amounts of NERSC hours are adjusted on a quarterly basis, by returning a portion of their unused balance to the corresponding DOE Office reserve. On Tuesday, April 10, we will perform the first quarterly allocation adjustments. If a repo has charged less than 10% of its allocation, then 25% of the unused balance will be returned to its DOE office reserve. For more information on allocation adjustments, please see <http://www.nersc.gov/users/accounts/allocations/allocation-reductions/>. ## Multi-Factor Authentication Now Available for Users! <a name="mfa"/> ## NERSC is pleased to announce the availability of Multi-Factor Authentication (MFA), a new security feature that can help prevent compromise of user accounts. With MFA, when you login you will enter your NIM password plus a One-Time-Password (OTP). At this time, when using MFA at NERSC you will get the OTP via an app (Google Authenticator) on your smartphone or tablet. The OTP will replace your ssh key for MFA-enabled NERSC systems - when you ssh to a NERSC system you will enter your password plus the OTP provided by Google Authenticator. You can reduce the number of times you have to re-enter your password and OTP by using the ControlMaster feature of ssh - see the web page linked below for how to use this. Additionally, you can also now ssh between NERSC compute systems without a password or key, regardless of whether you have enabled MFA. At this time, MFA is available for ssh access to Cori, Edison, Genepool, Denovo, PDSF and Data Transfer Nodes. We will enable it for other services in the future. Note that if you run automated remote scripts that reply on passwordless ssh keys, you won't be able to use MFA yet - we plan to have a solution for this use-case in the future. If you're unsure whether MFA supports your workflow you can test it by opting in in NIM - if you have trouble you can easily opt out again via the same menu. To give it a try, first read <https://www.nersc.gov/users/connecting-to-nersc/mfa/>, which will show you how to set up and opt into or out of MFA through NIM. Please contact the NERSC consultants via <https://help.nersc.gov>, <https://my.nersc.gov>, or <consult@nersc.gov> for any additional assistance. ## Call for Proposals: High-Impact Science at Scale on Cori <a name="his"/> ## NERSC is seeking proposals to conduct high-impact science campaigns using NERSC Cori supercomputer at scale. Up to 600 million NERSC Hours in total for allocation year 2018 will be awarded to research teams addressing scientific problems that require the computing capability provided by Cori's Xeon Phi "Knight's Landing" (KNL) nodes. A successful proposal would require the use of at least 2,000 KNL nodes to solve a problem, with a preference for proposals that exploit Cori's unique capabilities (e.g., using all or most of the 9,688 KNL nodes or making heavy use of the burst buffer). Previous awards were in the range of 10-100M NERSC hours. Data-intensive projects requiring large-scale analytics (statistics, machine learning, deep learning) are encouraged to apply. More information on requirements and how to apply are available at <https://www.nersc.gov/users/announcements/featured-announcements/high-impact-science-at-scale-2/> ## Frequent Reservations on Cori KNL Anticipated <a name="gbell"/> ## We anticipate that there will be more reservations than usual on the Cori KNL nodes for the next 6-8 weeks. We appreciate your patience during this time if your jobs do not have the same throughput due to these reservations. ## Come Work for NERSC! <a name="careers"/> ## NERSC currently has several openings for postdocs, system administrators, and more! If you are looking for new opportunities, please consider the following openings: - [Storage Software Developer](https://lbl.referrals.selectminds.com/jobs/storage-software-developer-539): Develop HPSS software and help evaluate and shape new storage technologies to meet the needs of NERSC users. - [High Performance Computing Systems Engineer](https://lbl.referrals.selectminds.com/jobs/high-performance-computing-systems-engineer-407): help architect, deploy, configure, and maintain large-scale, leading-edge systems of high complexity (e.g., Edison, Cori, and future NERSC systems). - [Computer Systems Engineer](https://lbl.referrals.selectminds.com/jobs/computer-systems-engineer-412): collaborate with scientists and conduct applied research and development, outreach, and training in I/O middleware for science. - [Machine Learning Engineer](https://lbl.referrals.selectminds.com/jobs/machine-learning-engineer-357): collaborate with scientists and conduct applied R&D, outreach, and training in machine learning for science. - [NERSC Exascale Science Applications Postdoctoral Fellow](https://lbl.referrals.selectminds.com/jobs/nersc-exascale-science-applications-postdoctoral-fellow-nesap-303): work in mutidisciplinary teams to transition codes to Cori and produce mission-relevant science that truly pushes the limits of high-end computing. - [NERSC Exascale Science Applications Postdoctoral Fellow for Data](https://lbl.referrals.selectminds.com/jobs/nersc-exascale-science-applications-postdoctoral-fellow-for-data-nesap-295): collaborate with scientific teams to enable the solution of deep, meaningful problems in data- intensive experimental/observational sciences such as cosmology, high-energy physics, neuroscience, and imaging. - [Software Engineer / API Developer](https://lbl.referrals.selectminds.com/jobs/software-engineer-api-developer-306): build a new system for tracking resource usage across our supercomputing environment, and create an API for this system and eventually the whole center.
